Answer: The length of porch is 18 feet.
Step-by-step explanation:
Given: The scale drawing of a porch is 8 inches wide by 12 inches long.
The actual porch is 12 feet wide.
Actual porch and the drawing are similar, then
Hence, the length of porch is 18 feet.
Answer:
I think the answer should be 54 pi centimeters but I can't see all the options, area of a circle is pi r^2 so if the diameter is 18, diameter = 2r so the radius is 9. pi 9^2 is 81 pi, then the same for the 3 unshaded ones and just subtract the area of the 3 white circles (27 pi) out of 81 pi.

Answer:
Ok so the two points that are given need to be in the form of y2-y1 over x2-x1, meaning the x value from the second set of points needs to be subtracted from the x value from the first set of points, and it is the same for the y values. Then that gives you the slope. You add the slope to the equation y=mx+b. The slope is m, so you put the slope in the m spot. If the slope were 3, it would look like y=3x+b because it is in the m spot. Then, you can choose any 1 set of points given and plug it into the equation. I am going to use the slope 3 , like the last example, and plug it in with the set of points. Say the point was (5,2), you will plug the x value, which is 10 in the situation, next to the the slope. The slope will then be 3(5). Then you will plug in the y value, which is 2, into the y place. At the end, the equation will look like this: 2=3(5)+b. Then you multiply 3 and 5, which is 15, and subtract 2 and 15 which will give you -13. The answer will then be -13=b. That is the y-intercept.
Step-by-step explanation:
The equation for perimeter is 2w + 2l. When you substitute this in you get:
2(3m+5) + 2(2m+3)
6m + 10 + 4m +6
10m + 16
